MANILA, Philippines -- For the country's most followed personality on Twitter, the upcoming elections should be all about the platform, not the personalities.

At the sidelines of a press conference held Tuesday night to launch her latest product endorsement, actress Anne Curtis said she has decided not to formally endorse any candidate leading up to the May mid-term elections.

"I choose not to [endorse any political candidate]. There have been offers, but no na lang," the 28-year-old Kapamilya star told ABS-CBN News.

With over 4.1 million Twitter followers, as of writing, the "It's Showtime" host is seen as a valuable backer to poll bets. Her endorsed products, which range from canned tuna to shampoo, are mentioned in her Twitter feed, enjoying brand recognition from her millions of followers.

For the elections, however, Curtis said she would rather stick to promoting causes, as opposed to being identified with a specific political candidate.

"I think I'll only do it if I believe in what they stand for, like if it was someone who's very firm with their [advocacy for] women's rights or something I believe in. I don't have to be out there in their posters. I can do it in my own way," she said.

On Twitter, Curtis has played part in calling for aid for victims of natural disasters, including those affected by recent flooding due to heavy rains in the country. She also helped in promoting ABS-CBNnews.com's Comelec Halalan 2013 mobile app last year.

Recently, she was tapped by the Australian embassy in the Philippines to help launch its official presence on social networking site Facebook.

On Wednesday, Curtis took to the popular micro-blogging site to express her support for the preservation of the environment and for children's welfare by re-tweeting a post of Akap-Bata partylist.
